Fwd: unstable behavior with 1.7.5


Hi,

For a couple years I've been running Cygwin on a laptop with Vista
without issues. Today I upgraded to 1.7.5 from 1.5.x. At first I just
did the upgrade, then after having instability issues, I nuked all
cygwin from my computer and did a fresh install. I'm having the same
problems.

Mostly I run cygwin to run X so I can display stuff to the screen from
my Linux machines, or to run latex/xdvi and use gvim as my editor.

Here are the symptoms:

1.I run most processes from xterm or rxvt which are spawned after I
run startxwin. Processes like gvim will just freeze for seconds at a
time before I get a response. Same with xdvi, and same goes with the
rxvt or xterm processes - I'll try to enter a command and it will just
sit there. This is especially bad if I start doing else like browsing
for a while. It's as if cygwin is being "put to sleep" or something.

2. I'm getting errors like this, often in conjunction with the
"freezy" behavior:

I am spawning processes such as latex and xdvi from gvim using
Tex-Suite, but the problems are not limited to this configuration.

3. When I click on a background cygwin window (like rxvt or xterm) the
windows OS will not bring it to the foreground immediately. It stays
in the background for as long as 10 seconds or so, or requires me to
right-click on the taskbar which seems to wake it up. During this time
period the CPU is not doing anything and the hard drive light does not
indicate significant (or any) activity.

I do have Windows Defender and Logitech webcam software on the
computer, which I read sometimes conflicted. I disabled the webcam
software and am convinced that Defender isn't the problem because it
only runs once in a while; however I will disable it if need be.

I only started having these problems with 1.7.5.

Thanks for any pointers.
