Menus not working properly

[Denzil]

Using version 5356 on Linux Mint 13. The menus and buttons do not respond to the mouse correctly. The mouse needs to be clicked away from the button in order for it to respond, and the menus do not stay opened, making it almost impossible to select menu items.

Could you start JOSM repeatedly and see if the bug remains the same every time?

Also a more detailed explanation would be helpful, to better understand the problem.

Same every time. The effect of the cursor is offset from the actual cursor position. Example: I click on Images, the menu appears, but only for as long as I hold the mouse button. If I move the cursor straight down, the Images menu disappears and the Tools menu opens. If I click on Imagery, hold the mouse button, then move across to Audio, then move down, I get the Imagery menu items, but the highlighted option is one row above the cursor position.

Tested on another PC also running LM13 - works fine, so is specific to this PC.

Hm, sounds like a Java or OS bug, not much we can do about. Installing Oracle Java may be worth a shot.

I know this effect from using Josm under linux displayed with Xming on a windows system. Not a josm issue.

I had the same problem (also with Mint) and found a solution. Open the .josm/preferences.xml and delete the two tags containing

gui.geometry
gui.maximized

After a restart it should work fine again. Deleting these tags resets the values for the window size. Somehow josm thinks that the window has a different size (once you close it in a non maximized state) which causes the mouse offset.

If the problem was already there when using josm for the first time, maybe it helps to adjust the gui.geometry to your screen geometry.
