I downloaded the latest version from the trial section. The same file name did not bother me because I usually go by file size and only if it is the same as the earlier one do I start twitching. This time the first version was 50,272 KB and the latest is 51,219 KB.

I uninstalled the earlier version and the new one went in fairly smoothly.
The hang at 71% was shorter than in the first version. However it still stopped at 97% and gave me the restart option window. I chose "yes" and it flashed a "The application failed to initialise..." before going into restart. I don't know if that is serious.

After restart the program appears to be working and the version number is 4.0 DL April 2 2008. The about window expands on this giving 4.0.4845.

The window drip down issue appears to be fixed.
