Background: - Been using BBO for several years - Recently upgraded to Windows 7 64 bit - Use BBO v5.2.6 - Do not wish to use BBO browser based version Problem: - v5.2.6 locks up frequently when(any)items are clicked - can happen at anytime; doesn't particularly matter what is clicked - lasts 60 to 120 seconds Have tried: - Changing "compatibility mode" to every version (Windows 95 through to Vista SP2) - always the same problem - Tried changing the "bbover.ini" file to "ServerHostName1=altport.bridgebase.com" and "ServerPort1=80" - always the same problem Questions: - Do any other users have this problem? (haven't seen any in the forum) - Does anyone know how to fix this problem? Thanks for any help!
