If i try now, it works ok...

The timestamp of Shadow4 in app folder is "19/09/2010 12:43 p.m." (DD/MM/YYYY). But which time zone? I'm in Argentina, and now time zone is -3. If the skin file is from 12 p.m. GMT+0, then i can download the skin "before" and install an addon at 10 a.m GMT-3. I think that if Rainlendar2 checks difftime > 0, it will use the original skin instead the updated one.

I'm not sure of this, could be possible?
If this is possible, then i will need to wait a couple of hours until installing an update...

It seems that at least on Windows XP extracting a file from the archive keeps its local timestamp which I'd consider a bug. But since there probably isn't anything I can do about it you just need to wait for for few hours before applying the addons.

It seems that Rainlendar prevents Outlook from closing.
Now when I close Outlook application while Rainlendar is running it still exists in list of processes and shows gray icon in tray "outlook is closing". I have to kill it manually. The same happens after sync with PocketPC (process and icon). If Rainlendar is not running, everything is OK.

Is Rainlendar doing something when you try to close Outlook (i.e. does the debug log show any activity)? Have you installed any addons to your Outlook which could be incompatible with Rainlendar?

Completely nothing is in debug log. But it seems that the problem disappeared after I disabled all the add-ins in Outlook and than reenabled back. Strange is that it showed up after I updated the Rainlendar from b93 to b95.
