It has worked before i upgraded it... any reinstalation doesn't work...
Why is it like this? MCCP Compression is on...
And it hangs always after i send command which start basics triggers...

Hmm...
Anyone has some idea?

Try it without the mccp emulation? I dunno if that shows in the debugger, but you might try logging in with the debugger open to see what gets sent. If it doesn't show in the debugger, you might need to log the raw input (I totally forget how to do it in CMud, since I think the command changed).

If Polish is a multi-byte language, though, that will definitely cause issues since CMud doesn't support them yet (that's at least a year or two off, based on the feature/bug list Zugg is working with).

I can confirm - one of my users discovered this as well, and I verified with 2.37 (I still use zmud, even on Vista).

On first connection everything is fine, and the user sees everything correctly (the New Connection log will seem out of order in these logs, as it starts negotiation before logging the connection)

If reconnecting with the same session/window, CMUD doesn't proper start decompressing, and the first thing the user sees is garbage - but after the first blast of the login screen, everything will be fine, and compression is operational as well.

Disabling MCCP fixes the problem, but this is the first I've heard of it. It works fine with ZMud 7.21 and Mushclient, though a user still using a v6 of zmud says it also happens for him sometimes.

Please post the MUD hostname and port so I can test this myself.

However, when you reconnect to a MUD, the server is supposed to reset the MCCP Compression state. A reconnect should look just like a normal connection. The server should not "remember" the compression state, because it's a different connection. The client and server are supposed to re-negotiate the options.

Someone can correct me if I'm wrong. Also, I haven't changed any of this since zMUD as far as I know so I don't know why it would work in zMUD and not CMUD. Perhaps you can post a dump showing what a zMUD connection looks like so that I can compare the two.
