Hello,

On one particular Windows machine with VB 3.0.4 I have a problem with
unresponsive configuration dialogs:

When I press Ctrl+G to open VB settings, it takes 12-13 seconds for
the dialog box to appear. When I press Ctrl+S to open settings for
VM, it takes 22-23 seconds for the dialog box to appear.

While waiting for dialog box to appear, VB freezes.

This problem occurs only on a particular Windows machine - on other
Windows machine and on Linux (both running VB 3.0.4) dialog boxes open
quickly (under a second for VB settings and two seconds for VM
settings - which is also somewhat annoying (since you still have to wait
two seconds for a simple dialog to open), but bearable).

What could be a problem on that machine?

Check with processexplorer what else is running and taking control.

The machine is under normal load. On another machine (where VB is responsive) the load is similar.
