Can't launch anything outside "Favourties" or "Files & Folders" using touchscreen

Thanks for reporting this bug. When using the touch screen, can you move between the categories on the left? When you click on an normal application in, say, Internet, what happens? Does it just not start or does itn not start and get added to favorites? Also, can you launch a folder from the Files and Folders category?

1. Yes, I can move between categories.
2. When I click on a normal application, it looks like I've tried to drag it a little. No permanent change though. It doesn't start, nor is it added to favourites.
3. Yes, I can launch a folder from "Files and Folders."

I'll try getting a screencap tomorrow, it's just hard to record a low-powered device like my netbook.

Yes, I have the same problem. Attached a video.

That video illustrates the bug I encountered perfectly.

I can confirm this bug. Also the same problem appears when using VNC (vino) instead of touchscreen. Attached xev output shows the difference between VNC, touchscreen and mouse "clicks", maybe it's related, because netbook-launcher seems to think that i am going to drag a shortcut (but not to launch it) because of this Motion_Notify events.

When clicking by TS/VNC, those Motion_Notify events call on_motion() handler in nl-icon-tile.c, which emits "begin-drag-move" signal if LMB is down. Maybe the easiest (and maybe the dirtiest) solution is to check if motion is happening at the same point (or near) where LMB was pressed. Attached file is an illustration of this idea (not a quality patch, i am not a coder). At least, now i can launch any app in any category with touchscreen (and still can drag it to Favourites).

I don't believe this happens with any specific hardware. I am using both a regular mouse and a touchpad. Both of them have this problem and it's been happening for as long as I can remember even on the old interface. As was said before it seems like there is absolutely no dead zone for dragging so it activates immediately even when the cursor is completely still.

I can confirm this bug with touch screen panel. (mouse is ok, trackpad ok)

Installed touchscreen module on an Asus EeePC 901. All is working like a charm, UNR with its big icons, scrollbar to the right, categories buttons is the perfect touch screen experience, astonishing, but this bug renders the whole thing quite useless and mostly annoying.

What I really don't get is why on earth should we drag the icons? To add a favorite there is already a favorite button. The only place we can drag them to is Favorites, no rearranging or changing categories... This for me is quite useless.
There should at least be, in gconf-editor, an option to disable the dragging, in my opinion.

If this was Off Topic, sorry.

Can anyone tell me if the proposed patch works, how can it be applied, and to what?
Do I need to download the sources of nblauncher (from where?) to my 901, apply the patch (to what file?) and compile it? Thanks for any help you may give.

cd # ChDir HOME
mkdir netbook-launcher # make directory for our code manipulations
cd netbook-launcher # chdir
apt-get source netbook-launcher # grab netbook-launcher sources from repo
cd netbook-launcher-2.1.12 # chdir to source dir
wget http://launchpadlibrarian.net/33315482/434502.patch # download my "patch"
patch -p1 < 434502.patch # apply patch to the source tree (1 file should be patched)

done. compile and install as usual:
sudo apt-get build-dep netbook-launcher ; ./configure --prefix=/usr ; make ; sudo make install ; killall netbook-launcher

now you should have this workaround applied, hope it'll be useful for you.

Hello,

Works really well.

I can confirm this problem too. I just packaged ilovemistakes' workaround and put it in my Asus T91MT UNR PPA: https://launchpad.net/~speijnik/+archive/asus-t91mt-unr
