Imagesource of char not working as expected in Windows

[Michael Kann]

The following script works for me on Windows XP Pro in a stack. I'll build a standalone and see what happens.

on mouseUp
   put "~" after fld "aFld"
   put "C:\Documents and Settings\zhangt\Desktop\imgFolder" into k
   set the defaultFolder to k
   set the imageSource of last char of fld "aFld" to "binfile:a.png"
end mouseUp

The image is only the height of the char it replaces. 

Can I assume that your first concern is to get something working rather than figuring out what might be wrong?

E-mail off-list any time. I'm trying to learn RunRev and it's fun to learn together.
