Excel popup dialog boxes are too small

Hi All,
Not sure if this is the exact correct forum but I have an issue with Excel dialog boxes being too small when running parallels on my MacBook Pro. In this case I'm using Oracle's ADFdi MS Excel plugin and when I try to submit a transaction the resulting dialog looks like this, note the vertical and horizontal scroll bars:



I'm wondering if there is anyway to get this box to open in full size by default. Thanks in advance for any ideas!

 

Are you using Parallels RAS (Remote Application Server) or Parallels Desktop?
For Parallels Desktop, you will have better luck on the Parallels Desktop for Mac forum:

Maybe under "Windows Virtual Machine"
