Topic: Call to OS function failed
Win XP, Graph 4.4.2 build 543
Whilst displaying a graph and moving the mouse pointer onto menu title or menu item,
the message "A call to an OS function failed" was displayed and graph no longer responded.
A Ctrl-Alt-Del was required to close graph. This occurred frequently, even after downloading
and re-installing (it happened to be the same version and build).
A couple of times, after waiting before using Ctrl-Alt-Del, the following message was displayed:
"Access violation at address 00A3A360 in module graph.exe. Read of address 00000004".
