Hi all, sorry for my poor English.
I am experiencing a bug using Potlatch on Ubuntu 9.10 64 bit platform with Compiz effects activated.
The problem is that mouse clicks have no effect on Potlatch, so Potlatch is totally unusable.
On Ubuntu 9.04 64 bit the problem didn’t happen, nor on Ubuntu 9.10 32 bit.
If I deactivate Compiz effects everithing works fine, but this is a friend’s laptop (he is the mapper) and he really wants Compiz.
Someone can reproduce this? Is there a solution? Thank you very much.
I suffer the same problem. Switching temporary to KWin helps, but that’s uncomfortable 
Unfortunately this appears to be a problem with Compiz and Flash Player in general, not just Potlatch. There are lots more reports of it at ubuntuforums.org.
