Hi Markus,
I managed to get Dimension4 to work properly with my W7/64 *prof* by the
following steps:
- tell W7 *not* to synchronize time via internet (beacause D4 is supposed to
do this)
- run D4 in compatibility mode for XP (under properties; not sure if this
mode is available on W7 home versions)
- tell D4 to synchronize every 5 minutes from a ptb server
- can't remember if running D4 in admin mode was necessary,but surely it
won't hurt
Another,maybe easier and more straightforward way for proper time
synchronisation of W7 is described here
including how to set the time intervals (haven't tried it myself so far but
is reported to work well)
