Occasionally, in LXPanel Preferences>General the scrolling arrows to set icon size gets stuck when clicked. Icons increases non stop till panel crashes. It happens once in a while & not sure how to reproduce. It could be an on-click/on-release issue.
More info for this bug: This bug is with Lubuntu Maverick. Note, it could be that the button is small and when on-click it scrolls and on-release, it stops. The problem might occur because one moves mouse slightly off the button after on-click and on-release action does not occur because of that.
Ticket moved from /p/lxde/patches/377/
I hope this issue is fixed in current GIT sources repository. Check it when possible, please, and report back if something is still wrong. Thank you very much.
