sry for this late reply...
You'll have to export T-Clocks settings yourself using RegEdit...
It's in: HKEY_CURRENT_USER\Software\Stoic Joker's\T-Clock 2010

Or use those CMD files I've attached ;)

edit @ 07/03/2015:
removed attachment. Those batch files are quite outdated and actually don't properly work with UAC enabled (they export/import to/from C:\Windows\System32 if elevated later)
The attachment had 87 total downloads

thanks char7 for that detailed report ;)
Hope I'm some when able to reproduce it myself (or someone else with time to test :P), otherwise it's hard to fix such thing.. (and sadly I'm not using 64bit^^)

clicking T-Clock once will open the calendar, clicking it again while the calendar was open will just reopen it and not just close it as the default clock does.

ehm... why? xD Clicking once opens, clicking again hides as of now..

well there's a catch actually.. you shouldn't have a double-click action for your calendar key defined... in that case it'll open again even on single-click.. this is due to the time delay involved. And there's actually nothing that can be changed about it... except for some vodoo magic as using a bool to set a flag and once no double-click occurs in time and the single click would be executed, we'll just ignore it as the calendar already hid. That'll be ok and working :P

so not even the context menu works? that's strange...
The clock is still there right xD?

Well... I didn't make any change that I know of that could have caused this...
So I need to ask you which OS (including 32/64 bit), where is your Taskbar located and does it happen all the time? (Win+L, then go back in again)
And it worked with Stoic Joker's and LonelyPixel's build?
