Hello all,

some minutes ago I got an AV (~ third time now). Maybe be following info is useful:

I've observed this AV in my RAD Studio 2007 since yesterday. It appears very often, but only when editing one specific file.
Now I came to the point it appears when I type every single letter. Appears only when editing strings ("").

It makes programming really annoying.

Both seems Strange. Could you help to debug it using our debug version?

http://www.cnpack.org/download/d ... 0.9.6.570_Debug.exe

The DLLs in this version contain debug information. We can get exact stack info in our DLLs instead of [0749E045]

我的也是CNWIZADS_D14.DLL出问题了。

楼上可否帮用Debug版本记录一下信息？用Debug版的话，弹出的调用堆栈中，CnWizards中的地址会包含更精确的信息。
