Hi and thanks for any input before hand. I am following the "quest tutorial" instructions from the TES CS wiki and i am having trouble with CTD's. Ive googled it and have found no fixes, much to my dismay. The CS crashes when i try to add dialog to any topics ive added to my quest ((click topics button-->> add "greeting" topic-->> r-click and select "new"in the info window too add text-->> crash-->> curse the CS-->> try again)). I have worked through most of the tutorial before and have gotten it to work, until now. Im wondering if it has anything to do with the fact ive switched os's, from XP to Win7? anyone else experienced this?

You're right.
It has to do with Windows 7(I think on Vista too, but I'm not sure about that.).
Plug in a microphone or headset and it should work.

Excellent! thank you very much that worked. Oddly enough plugging in a microphone worked.
