Good  morning,
I have an app which behaves very strangely when I run it on a PC with a small screen. When the app starts up, it creates an empty diagram and displays it. Each time, the diagram has a large red cross through it, and I get an exception about paint. If I close the diagram (not the app) then recreate the diagram, all is ok.
Your help would be appreciated.

The exception is show below:


App up time:       00:00:15.5468750
Total memory:      1015Mb
Available memory:  642Mb

Exception classes:   
   System.ArithmeticException
Exception messages:
   Overflow or underflow in the arithmetic operation.
