Magnus,
Based on your description is sounds like there is a script error on your page (IE is not stupid in regard to "return false"). That would explain why the form doesn't not submit correctly and why blockUI does not display. Do you have IE's script debugger enabled? Is there a link you can provide that demonstrates the problem? Without something more to look at it's difficult to give you much assistance. But my money is on the script error. Mike
This works like a dime in FF but in IE it's all messy. First of all I can't get IE to stop following the form submit. IE always tries to submit the form regularly but my javascript code says "return false;" - FF understands that but IE is stupid (or maybe it's me, I don't know...).
