Sync Error OPP&ID

Hi

Any ideas what I need to do to fix this sync error, am currently running the project database on my local c drive. one suggestion that has been made to me is there might be something wrong with the View Window (viewports) if this is the case any ideas how I can fix this.

Bentley.Plant.ModelingFramework.SQLPluginAdapter - Synchronization stopped because of error: 'SplitterDistance must be between Panel1MinSize and Width - Panel2MinSize.'.

Thanks
