edited to add - Problem is fixed, strange solution

After months of working of working on terrian, buildings, NPC's etc, I am finally to creating a couple of quests and being done with a mod, however, I have a problem I can't figure out. When I try to add a info to a topic the CS crashes. I go to quests, then the topics tab, create a new topic or select an exixting topic and then try to add a info (response) by right click/add. Every time I do that I get the old CS has stopped working, click here to close error.

More info:
This is my first quest creation and I have been using the wonderful Oblivion Modding For Beginners tutorial and am on lesson six: dialogue, which is found http://cs.elderscrolls.com/constwiki/index.php/A_beginner%27s_guide%2C_lesson_6_-_Quest_Dialogue. I also confirmed the process on the page - Category:Editing Dialogue found http://cs.elderscrolls.com/constwiki/index.php/Category:Editing_Dialogue. As I said above I originally creaded a new quest the a new topic under the topics tab. Then I right clicked in the info section and had a chice of add, copy, delete, or move to quest and selected 'add' at hich time the CS crashed.

I have tried with a new topic several times, with a vanilla quest, with another persons modded quest. I have tried everything I can think of including unistalling/reinstalling the CS, rebooting and crossing my fingers. But, no matter what is loaded in the CS (vanilla or any modd), I can right click and copy, delete or move to quest with no problem but if I right click and select 'add' it crashes.

I started this last Thanksgiving, have a few hundred hours into it, have figured everthing else out from all the tutorials and searching the forums, but this has me completely stumped. Any help would be greatly appreciated.

Thanks

Plug in a mic (or any plug/wire) in your computer's microphone hole, see if that helps.

I had the same problem when I try CS on Win7 64bit, Every time I tried to add a topic it crashed, and now when I'm back on 32bit version everything works fine, so that may be a system problem that cannot be fixed

That's not very reasuring but thanks,. I am using a newer vista 64bit PC and that is my only option at that moment. I'll keep trying.

You, my friend, are a genius. I love you and I don't ven know you!

I plugged my headphones into the mic jack, tryed it with a known good mod loaded into the CS and it worked great. Just to be sure I unplugged it, tried again and crash. I plugged them back in, loaded up my mod and it worked perfect.

Thank you, thank you, thank you!
