Problem with 1.2.0.3 in windows 2012 R2

Post by blo »

hello,

under windows 2012 R2, with ultraVNC 1.2.0.3 , when you press the combination of keys alt gr+ (anything), seems that uvnc(server) hangs for a seconds.
In my keyboard (spanish), for example, to put @ you must press alt gr + key "2", and also \ is a key combination, so you know, it's hard to do remote support with freezes of about 2-3 seconds every time you put an \ in a path...

We make some testing, and we can say that the problem happens whith uvnc 1.2.0.3 in a windows 2012 R2 (with desktop) connecting from a w7 with also uvnc 1.2.0.3, an happens too connecting from a w7 with uvnc 1.1.9.6. Beetween two W7 with uvnc 1.2.0.3 seems that the problem is not happening.
We tried with w8 hook activated and deactivated, with the same result, a little freeze of about 2, 3 secs, seems like the uvnc server(service) restarts or reconect (sometimes we see in the w2012 monitor when this happens, that uvnc icon changes from yellow to blue for a second), and when the remote control returns to life and screen refresh, some keystrokes have been lost. (i.e. you want to write \\server, sometimes it only make \ or \server or nothing...).

I guess this could happen also in windows 8, but I can't test it.

Please test by renaming uvnckeyboardhelper.exe uvnckeyboardhelper_old.exe.
win 8 ( 2012R2) lock special keys like alt-tab.... we made some helper to unlock it, but on some systems
this has some site effects.
If the file doesn't exist, it isn't used.

It's better to have alt-tab not functioning that altgr.
On our keyboard altgr + 2 = @ keyboard (be), but we can not repat your issue.

If you don't hace the issue without the helper it would already limit to search to this function interaction.

Runing as sevice ?
Application with runas admin ?

Hi,

It's running as service.

Same problem (right alt not allowing to type international characters) on Vista, service, 1.2.0.6.

I have no "uvnckeyboardhelper.exe" file, but see an option "alternate keyboard method". Regardless of the option it does not work.

This problem makes uvnc unusable for me. Any input I can provide to solve the issue?

I see tightvnc does not exhibit this problem. Setting encoding to "tight" does not help ultra. Any suggestions?
