Well, it's not really the {} button any more, but the 'Check Brackets' button in the top right hand corner.

When clicking on this button multiple times, the drop-shadow (which is the 'Enter' action when not in the editable dialog) isn't left in a constant place. It swaps between the 'OK' and 'Check Brackets' buttons.

[NOTE] Once again, yeah. Not huge, but still..

Interesting. If you click slowly, it will change every click. If you click more quickly it will change every other click.

lol how do people find these things :p

I pressed the button, an didn't see any movement.. So I pressed the button a few more times, and noticed the shadow moving..

Basically, I expected something to happen when I pressed it (was doing lazy-coding), and it so happened that I didn't make enough mistakes for it to find.

its not called a shadow, its a highlight and yea its odd.

Not sure if this related in any way.
Besides the numerous problems i'm having with this mIRC release
I opened the script editor to the remotes tab, the button that's supposed to check the brackets had the icon for the disconnect button on the toolbar, then when i focused the aliases tab it disappeared and had no icon at all, then the popups tab showed the check, then back to remotes and i had no icon at all, it's sometimes there, sometimes not.
I'm finding this release a real pain

Works fine here. What OS are you using and is this a clean install?

Windows Vista, and yes a clean install.

nice thx.

I can reproduce this as well, it seems to be Windows automatically changing the hilight on the buttons when the focus changes, I haven't been able to find a way around yet.

Thanks this has been fixed for the next version. This was due to Vista requiring a different method to display icons in buttons when using the Windows Vista Classic theme.
