[plt-scheme] Re: new bug test results for the intermittent file explorer hanging problem previously reported

For the record, I recently disabled Aero (Vista's default GUI) and the
problem seems to have disappeared.
So I switched back to the standard file-dialog with:
(preferences:set 'framework:file-dialogs 'std)
No need to restart DrScheme.

For those who need to stick with the 'standard file-dialog, to quickly go to
a given path, it is possible to paste it in the filename text-field, and the
dialog will automatically move to it (it's also fun to watch).
