[Dx4win] Windows 7 64-Bit Pauses and Freezes (UPDATE)

[Byron Peebles]

Friends:

Using the Task Manager and the Configuration Manager resource mentioned 
in the previous post, I am feeling better about eliminating the problems 
I was experiencing with my Windows 7 Ultimate system and DX4WIN.

First, the change from the Display Windows Manager (dwm.exe) from Aero 
to Classic themes seems to have made the windows faster.  As I continued 
to look for anything that used more resources than DX4WIN, I also 
removed a Microsoft Office utility that is for shared document caching.  
It seems like the Install script for Office adds that to your Startup 
programs and I will never share an Office document from this computer.  
then, two Adobe Acrobat products installed themselves to make my PDF 
reading faster in some way and they are now not part of the system 
startup and background processes.  When these changes are combined, the 
system behaves better, at least so far.

Second, I found a configuration error in the system that had really bad 
side effects.  When I was attempting to get the MMTTY RTTY software 
working, I have set the audio output device to default to my Ten-Tec 712 
USB-Sound-Card Interface.  I had also set the Mic input to PTT on the 
Ten-Tec radio.  The result of this mistake is that my system sounds, 
startup, spots, etc were being routed to the radio, not the speakers, 
and were keying the radio.  Not at all a good thing, since I have to 
assume those sounds could be heard, even though I set the radio to one 
watt output when I'm not in QSO, just in case.

So, one set of changes to minimize overheads on the combined CPU/GPU of 
a low-end, low-power motherboard and a secon change to reverse a 
bonehead configuration mistake that I made in a last-ditch effort to 
make something unrelated to DX4WIN work.

Again, time is the real measure of resolution, so I'll give it a week or 
two of active CW work to see if this is truly resolve.
