Wierd Problem : publishing swf two times before it works?

hi guys, I just got flash 8 a few days and i think this problem is a little strange but sometimes when i do changes in my swf file. I have to publish it about 2 times before my html file updates.

now i’ve been using flash mx,and mx04 and i never had that problem?

im using a flash mx04 file saved as flash 8. I have to publish two to three times to get it to finally update? Is that normal?
