I'm a newbie in flash. I finished my degree about 3 months ago and have been
learning Flash with Actionscript since.

I am going crazy because no matter how hard I try, unexpected errors keep
showing up in Internet Explorer. Mozilla Firefox works perfectly, almost the
same as when I test the movies in Flash. I am considering making Flash
development my career and need to know if the error is in my programming or if
Internet Explorer is to blame. I am building a site for somebody right now,
and I don't know how to explain the sudden image resizes, disappearing
preloaders and other strange phenomena. My biggest problems are loaders
constantly changing sizes and preloaders not appearing to indicate loading

Should I tell people to download different browsers to view my Flash sites, or
is there something I can do to make Internet Explorer work correctly?
