I'm on Ubuntu 9.10 Gnome, I'm using version 0.9.0+svn, installed throught Ubuntu Software Center.
I've met some bugs: (all on popup window)
-Alt + C it's just not working
-Right clicking after selecting some test (to copy) works fine at the beginning (at this time, the mouse pointer looks like that extented "I"), but after several uses the mouse pointer becomes a hand (like the one that appears when you hold ALT and hold left click to drag windows on Gnome), and when you right click after selecting text, the selection moves to other text on the window, so you can't copy what you selected.
-Alt + Tab is not working when the popup is on focus.
-The popup will open minimized (or not in top of the other windows) after the "hand bug" starts to happen.
When this happens, the only way to fix it is to restart Golden Dict.
It's my first time submitting a bug, so if I'm missing any info please let me know and I'll add it right away.
Edit: Found another bug, after the bug begins, the popup's title will no longer be the word in query, but an old query (probably the last one queried before the bug began)
