$isdde(test) makes my mirc freeze, if the server "test" doesn't exist. If the server exists, it returns $true (how it should). This problem accured first after reinstalling my mp3ad+ script, which uses $isdde. (mp3ad+ can only be used with NNScript.)
But now I can't use $isdde even, if my script is unloaded.

I'm using WinXP Home, mIRC 6.14 with NNScript 3.81. This combination works great on my other machine.

Without that script loaded it simply returns $false. I suggest you contact the addon/script author and have them check out the code - it doesn't seem to be a bug within mIRC.

Tested on 6.14 / XP Pro.

Regards,

The problem is: I am the author of that script. And as I said, it's all working on my other machine, not not on this, even if my script is unloaded, so perhaps my script caused that $isdde isn't working anymore, but it's now in mirc generally. (But how could that be?)

maybe the DDE Service at your winxp home is deactivated - take a look at it

It's working great, if the dde-server is running, only if it's not running, mirc freezes.

This usually indicates that there is another application (or possibly a service) running on your system that is using DDE incorrectly, and this results in the freeze problem you are seeing when mIRC itself tries to use DDE. If you try closing all other background applications, does the problem go away?

Thanks Khaled,
I closed (almost) all my background applications and then $isdde(...) returned $false, how it should. After starting the applications again it worked, too, so I don't know which app caused the freeze.
Thx again.
