#69 hangs in 2.4.1 when opening file that was saved with OOo 3.x

[Christian Lohmaier]

You cannot use OpenCards in a mixed environment with both OOo 3.x and OOo 2.4.1, since OpenCards in OOo 2.4.1 hangs when it tries to load the lerning-data from a file saved with OOo 3.x

(I guess it doesn't dismiss the "new version of OOo is available message" that pops up when you open the file manually - not sure though, as no such dialog is visible when using long-term-manager, just the pulsing progressbar that shows the filename of the file that is loaded)
