mintty window won't open


Hi all,

I switched from rxvt to mintty yesterday, and it worked great all day. However, today when I try to open a new mintty window from within an existing one, nothing happens. The process starts, but no window appears. This happens when attempting to open both 0.8.3 and 0.9b2 windows from a 0.9b2 window. The broken window also does the same thing to tkdiff but is able to run xterm without problems.

Oddly, using the shortcut from the start menu (0.8.3) still works, and any windows I fire up from it (including 0.9b2) work fine after that and can in turn fire up their own new instances. The broken windows are also permanently in alternate screen mode as far as mouse wheel goes (up/down arrow keys instead of scrolling the buffer) and their scrollbars are disabled even though they have many hundreds of lines of scrollback.

Running strace on a broken mintty instance shows:
220 5944199 [main] mintty 2908 peek_windows: window 4(0x0) ready

25103 5975642 [main] mintty 2908 select_stuff::wait: woke up. wait_ret 2. verifying
The above is repeated slightly more often than once a second and is the same every time. I don't know if this is relevant.

I'm running cygwin-1.7.7-1 with XP Pro SP3; mintty-0.8.3-1, and mintty-0.9b2 built manually from source.

I've suspended and resumed my machine several times since those windows were opened, maybe this has something to do with it?

Thanks,
Ryan
