Hi i have a Problem with my mIRC .

Every Time i want to write something in the Writing Box and i press a key on my keyboard an error happend .

Now i post the error:

-------------------------------------

Microsoft Visual C++ Debug Library

Debug Assertion Failed !

Programm: C:\Programm Files\MIRC\MIRC.EXE
File: dbgdel.cpp
Line: 47

Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

For information on how your program can cause an
assertion failure, see the Visual C++ documantation on
asserts.

(Press retry to debug the application)

---------------------------------------------------

If i press retry then a new error message comes up where it says that mIRC made an error at ISNSYS.DLL ....... then mIRC crashes . if i ignore mIRC crashes too .

PC Information :

OS: WinME
mIRC: 6.12 ( i think it happens with all versions )

Can someone help me ? I have uninstalled and reinstalled mIRC a few times the problem cames every time.

Please say it if you need more information .
