I am thinking of how to write a fix for this.
For now you can get the phone working by setting your windows so that your calculator is the same size as mine.
I can't work out how to make my calculator bigger, so I can't tell you how to make yours smaller
Can you think of anything that you've set on your WindowsXP that would make the calculator bigger? If you can then change it back for a temporary fix.
I know that whis is not ideal because you are in 1280x1024 and you may find everything too small to read (that's probablty why you made things bigger to start with)
Thanks for helping me debug this!
I will keep you posted with my development of V1.21 which will fix this for you.
