<html> <body> I had some problem.<br> My problem was caused by driver of printer. There was a series of HP drivers that were a bit buggy and by that I mean they turned off the floating point exception handling and never returned the state. <br> You might want to save the state before the call, then return the state after the call.<br> You can try if is this problem add a new printer and set this new printer like defaut (for example print pdf).<br> Daniele<br><br> At 12.55 11/11/04, you wrote:<br> <blockquote type=cite class=cite cite="">Hi,<br><br> I am getting a lot of Exceptions like this:<br><br> "MyApp caused an exception of type 10H in module Quesa.DLL..."<br><br> when running Quesa on a Windows 98 machine.
