OK The bug is fixed. Thanks to bkSpeedo for reporting the problem.
New version has been uploaded and can be found here.
Tha manual is here
Installing the new version will mean that the database will be re-installed as well. If you have models you need to preserve then I suggest using the Alt-PrintScrn method to copy a screen capture to word. There is another method but it involves finding and copying the Database file which is a little involved because it is not in a normal location. If anyone wants to try this method let me know and I'll post instructions.
To install the new version you must first un-install the old version. Just go to control panel and then add/remove programs. Then just install the new version as before. The microsoft apps do not have to be downloaded.
