I'm using Winstep Xtreme V4.11 (not yet registered, though that's in the mail)...
I've noticed an odd issue with the date in the system tray... errr, I mean Notification Area... the date is shown as dd/mm/yyyy, though my regional settings specify mm/dd/yyyy ... I don't see any option for correcting this, and it's a bit confusing!!! Is there some back-door way for me to correct this setting?

The date in the system tray actually uses Regional Settings but in an indirect way (not a perfect solution, I know): it checks to see if the time (clock) is set to 24 hours or AM/PM. If AM/PM then it displays the date in the English mm/dd/yyyy format, otherwise it displays it in the dd/mm/yyyy format.

So this happens because apparently you have your clock set to display the time in 24 hours format.

Yes, I use 24-hour time, but that does not mean that I use European date/time formats... I'm in the U.S. (California). I would request that you try to schedule an update that uses the Regional settings literally... any chance of that getting in the pipeline fairly soon??

I 'fixed' it already in the source code, but I can't make any promises as to when the next release will be.
