Testing with win32 1.0 13637 client against a 1.0 13641 fedora 23 server, when opening the Session Info (either with the shift-alt-F11 keyboard shortcut or the tray option) the client disconnects with the following traceback (posting the traceback, the full error message was long so I'll also attach as a separate file).

Checking with 1.0 r13520 win32 client the Session Info opens as expected (with or without opengl enabled).

Double checking the 13637 win32 client without using the --opengl=on flag (to get around my Intel driver), I also see no errors. Not sure if this is an Intel issue, but I think maxmylyn ran across the same thing with Nvidia.

Additional note - while poking around osx client issues reported in #1302, I began seeing this behavior in the osx 1.0 13637 client as well, but irregularly (maybe the third time I tried to open a Session Info window), and I was seeing it on the osx client whether I forced the opengl=on or not.

Ohh, and when the osx client disconnects, it is also hanging, requiring a force quit.

This was caused by r13639 (debugging of video regions, see #967#comment:27) and is fixed in r13642 + r13643.

Is this related? Does it occur if you don't use session info?. If not, please file a separate ticket.

D'oh - downloaded win32 1.0 r13644 client, but something must've gone awry in the build, because I can't install (windows 8.1 keeps prompting me to search for an app to open it).

(The osx client disconnection hanging seemed to only be happening with Session Info opening triggered disconnections, by the way... but the new osx client build seems to have gone similarly awry. I'll double check when I'm testing for #1302 to be sure though.)

I've posted new builds and included both the EXE and ZIP version.
Also, can't you make your own builds?

Huh, didn't even think to look for a .zip version.

The .exe you posted is not installing though. Trying with the .zip, it took so long to connect that I thought it wasn't going to work, but in the end it did connect and I was able to open Session Info without any problems.

Closing.

(And no, I can't make my own win32 client builds, but I can ask Smo nicely. Not sure the state of his build system currently, but I'll ask him double-plus nicely and see what happens.)

I have tried the latest EXE as well as a few more older revisions, on winxp, win7 and win8.1. Works fine every time, so my guess is that you're doing something different.
When did the problem start? Did you verify that it isn't a problem on your system by installing a known "good" version? What build revision is the first one to fail? etc..

Maybe I was just having issues with my downloading yesterday?

Just downloaded a new copy of 1.0 r13673 and launched, no problems. (I had been able to install previously downloaded builds, just not the ones downloaded yesterday.)

I'd close this again if I could, as is, I'll just scratch my head over what happened and move on.
