I use these versions:

[eric@pc ~]$ pacman -Q winswitch
winswitch 0.12.16-1
[eric@pc ~]$ pacman -Q xpra-winswitch
xpra-winswitch 0.6.0-1

And here are the errors... I can't really distinguish between 'serious' errors , and 'non-important' errors

I can do some more tests, just tell me...

After upgrading a linux server to openssh 6.7, I'm no longer able to connect to it from MS Windows (winswitch 0.12.20). In the server's log I see "fatal: Unable to negotiate a key exchange method [preauth]". I have no trouble connecting to the server via putty.

It seems that this is a twisted-conch issue: ​http://twistedmatrix.com/trac/ticket/7672

However, I assume that even once that's fixed, some work will be required on winswitch's part, too, even if only to create a new build; so opening a ticker here, too.

Using xfce4's terminal the '<' and '>' keys are fine. Using the same terminal and going through xpra, < (lt) is > (gt), but > (gt) is still correct, and , (comma) and . (period) are still correct.

Without xpra: <> ,. With xpra: >> ,.

I can copy/paste a '<' from a non xpra window and it works as expected.

Same thing happens with Xfce's Mousepad 0.2.16 and Terminal 0.4.7.

This is with aur/xpra-winswitch 0.0.7.22-1 aur/parti-all 0.0.6-2 is fine and does not have this bug.

Both Xfce's Mousepad and Terminal behaviours are correct in terms of '<' and '>' when using the xpra from parti-all.
