I hope the above attachments sent by apport-collect are appropriate. I tried to follow David Barth's request in https://bugs.launchpad.net/netbook-remix-launcher/+bug/456229/comments/1 and the instructions at https://help.ubuntu.com/community/ReportingBugs.

On my Dell Inspiron 500m, the problem existed already in 9.04 Jaunty, and got worse in 9.10 Karmic beta and release. I'm running 9.10 Karmic release from the USB stick created with unetbootin, and 9.10 Karmic beta installed on a 4 GiB CompactFlash card replacing the hard disk with an adapter.

Here are my results with different memory configurations and UNR versions.
DIMM A / DIMM B / UNR version: symptoms (see descriptions below)
-----------------------------------------------------------------
1 GiB 256 MiB 9.04 release: A (bad)
1 GiB 256 MiB 9.10 release: B (worse)
1 GiB none 9.10 release: B (worse)
none 1 GiB 9.10 release: B (worse)
256 MiB none 9.10 release: B/C [very slow of course, unsure]
1 GiB 256 MiB 9.10 release: B (worse) or C (worst)
256 MiB 1 GiB 9.10 release: B (worse)

Symptom A (bad): In Jaunty (1GiB+256MiB), application icons did react when the mouse cursor was somewhere way off to the left from the actual icon. IIRC, the category tabs worked quite ok. I think this is the same as the original report and most comments above (e.g. #7).

Symptom B (worse): In Karmic beta and release, the category tabs only highlight with the mouse cursor on or to the left of the category icon. No highlighting happens if the cursor is on the right side of the icon, the label or elsewhere in the tab. Also, it seems that the "active area" is horizontally "striped", i.e. the tab reacts at only certain vertical coordinates. Clicking on application icons doesn't work at all. Icons are never highlighted when hovering on them, and they don't respond to clicks. Changing "Visual effects" from "None" to "Normal" doesn't change the behavior. Desktop effects work ok in other application windows.

Symptom C (worst): On two occasions in Karmic release, the category tabs reacted extremely sporadically, and the application icons never reacted at all. Changing "Visual effects" from "None" to "Normal", the launcher was "faded" (partially transparent) and totally unresponsive to the mouse and the keyboard for about 1-2 minutes. After it recovered, the behavior was the same as with no visual effects. Desktop effects worked ok in other application windows.

In the panel and all other applications the mouse works perfectly.

I always get the same symptoms with the native 1400x1050 and also a lower 1024x768 resolution.
