New in Version 6.2c:
This version fixes a problem with the background image on multiple monitors on Windows 10.
New in Version 6.2:
Once again Microsoft made incompatible changes in Windows 10.
When you update to build version 14332 you will get an error 309 from older PTBSync versions when starting the Trayclock.
The reason is that Microsoft has changed the bahaviour of the Windows themes.
This was a difficult fix because the internal functioning of the Windows clock is completely undocumented.
New in Version 6.1b:
Fixed some very particular problems that have been reported by some users.
NOTE: If your PTBSync 6.1 is running fine, you do not need this update.
New in Version 6.1:
The problem with the download server has been solved.
PTBSync 6.0 was already running perfectly on the Windows 10 preview, but before the final realease Microsoft has changed some more things.
Version 6.1 has been adapted once again to the final Windows 10.
Errors during the installation have been fixed.
New in Version 6.0:
PTBSync has been adapted to Windows 8 and Windows 10 preview.
(It is really strange that there were bugs in PTBSync 5.8 and nobody ever reported them!)
The desktop calendar works now correctly with all 6 desktop wallpaper modes and with slideshow and on multiple monitors.
The trayclock has been changed for Windows 10.
Additionally PTBSync uses a newer graphics library that supports all image formats.
Note: PTBSync 6.0 requires at least Windows XP with Servicepack 2.
New in Version 5.8:
Some people reported to get an error from the weather server: "Invalid location provided".
The reason is that Weather.com has changed the codes of some cities and other cities were removed or added.
New Feature: Online city search.
