Help Please...going crazy here!

Hi, for the last 3 days, I have had very strange things happening when I list, that have never happened before, and I know how to use this site. It is very intermittent. ok - first when I go to chose a category, I will get the pop-up box telling me "if you leave now you will lose your listing..." I am only trying to choose a category! So then if I leave the first category blank and go to the second category I can choose a category then I have to copy the cat. numbers and place them in the first cat. box. Then when I go back to the 2nd cat. to erase that number I get the pop-up box again telling me I am trying to leave the page again! I also am not able to schedule any listings, every time I click on the calendar it just blinks on/off and I cannot choose a date. This pop-up box also does this when I am trying to choose an image. I know I am doing nothing wrong here, as I said before, I have been listing here a long while now. Then it also hangs when I try to save a listing and when I edit an image on the listing page. This is driving me crazy for 3 days now. The only way I am able to create a listing is to try to save it and go back, and keep trying over and over and finally I can get it to work, but its taking forever for me to create a listing. I am yet to be able to schedule any listing. Please help, before I go any more crazy!!!!!!!

I have contacted support, no answer yet though, I just cannot stand it any longer!
