Simple Dialog Application, Screen updates stop and or don't display correctly.
Multi-threaded to communicate via connected sockets, serial ports, pipes, events, user created messages.
Writes to a text log file (this keeps happening when the screen updates stop).
Works just great for 55 minutes, then the screen updates stop.
A list control in the dialog seems to keep updating as required, but
a multi-line edit control (write only, duplicate of the text log) stops, as well as
a number of static text controls, (one is a digital clock) both text and background color updates.
A child dialog can be brought up but doesn't display correctly.
No memory leaks are reported when the app is halted in the debugger (VS 2005 standard).
I must have something really foobar`ed.
Any thoughts as to how to find out what?
