[Dx4win] DX4WIN locks and uses 99% CPU

[Tom Brown]

I've been using DX4WIN version 6.03 everyday for quite a long time now on the same Windows XP PC (Pentium 4  2.6 GHZ) without any problems until now.  Recently, every now and then I will come back to my PC where I have left DX4WIN running with Packet Telnet connected and I will observe the following.  All DX4WIN windows that are opened have gone blank (white) and the title bars are all appended with "(Not Responding)".  My PC's CPU is being 100% utilized and when I look at the Windows task manager, it shows that DX4WIN is the culprit sitting at 99%.  I have to kill the DX4WIN process to relieve my PC.  The only other things running on the PC at the time are MS Outlook express listening for e-mail and Norton Internet Security.  These have not been recently added and have always been running fine with DX4WIN.  The only thing I do is keep current with Windows Updates and Norton Updates.  I did recently update the DX4WIN country file, but I can't imagine that causing this.  Anyone seen this, have any ideas on how to troubleshoot?
