If I double click on the date in the tray, the calendar pops up but goes away after a fraction of a second. I have to double click multiple times before it stays.

Err... and why are you double-clicking when a single click gets the job done?

A single click brings up the Date and Time dialog with the clock in it. A double click brings up the dialog with the calendar, main clock, and alternate clock in it. Lots of times during the day I just need to see a calendar for the current month.

Sheesh! I just tried single-clicking on the clock in the Nexus and got the calendar dialog. That just made this bug trivial.

You see, that should not happen. Showing the Date and Time dialog is a 'fail safe' mechanism in case showing the simple clock + calendar does not work for some reason.

So, a single click on the taskbar tray button should bring up the calendar as does clicking on the Nexus clock module.

What version of Windows are you running again?

Windows 7.

Yeah, me too, and here I don't see a problem.

Ok, try something for me if you don't mind. Restart Winstep Xtreme.

Now left single click normally on the taskbar clock button and *wait*. Count how long it takes for something to pop up (what pops up? Date and Time or the Calendar + Clock?).

Now do the same on the dock's clock module. What are the differences?
