Hello Bruce and all others,
after playing with a webserver, just modifying the picture properties of date and time on the webserver-window (below that statistics list) I recompiled the app and got 306 errors!
I have added "screenshot_doubledots.png" to this posting.
After some wild guessings, I went to the webserver extension, Buttons-tab, checkmarked all buttons, recompiled and the errors were gone.
Went back, unchecked all buttons, recompiled and again the app runs fine.
Strange behavior, just wanted you let to know.
