I found that microB has problem in openning local swf files, i have tried to use both web page -> open page and open file, neither works. It shows in progress while only increasing the '/' in address line. There must be some bugs in it. I have tried opera, it can open the same file without any problem.
Would someone shine some lights? Thanks.

forgot to mention the os, i am using latest os2007 and with the most updated microB.
