No. While script is executing nothing much else happens. The settimeout allows the window to update the status bar. Try a forever loop and see what doesn't happen. > >2.) Next I decide to replace the boring text with an animated GIF! I >replaced the first line to be: > resultDIV.innerHTML = '<TABLE ALIGN="CENTER" BORDER="0" >HEIGHT="100%"><TR><TD><IMG >SRC="images/load_data.gif"></TD></TR></TABLE>'; > > Problem: the GIF isn't animated.

Not that I know of. > >3.) If I place a <script>alert('something here')</script> in my >stylesheet, perform a transformation, the script never gets executed... >is it possible to do this? > No. simple <script elements are just output to the result tree. <msxsl:script elements are executed during transformation but use only the basic language. alert is a method of the window object so isn't available.
