UM 175 & Windows 7

Wondering if others have had same experience?  I use my 2 mo old HP laptop on DSL at home & VZ broadband (UM175) when traveling.  Started getting "blue screen of death" multiple times during each Broadband login session.  HP tech support checked hard drive & RAM - both fine. Verizon tech support provided option to enable NDIS (Network Driver Interface Specification) - which somehow allows the VZaccess Manager to function as if it is a network connection rather than a dialup connection.  Their email stated "it appears you are experiencing a software related conflict with VZAccess Manager".  Seems odd to me they would not provide software update if there is a known conflict???  So far, I have used the NDIS option for 2 days & no BSOD so maybe it solved the problem.....
