Vista 64 Home Prem

I own DVDFab and am using on a new toshiba laptop, details are;

Microsoft® Windows Vista™ Home Premium
Version 6.0.6001 Service Pack 1 Build 6001
System Manufacturer TOSHIBA
System Model Satellite A305
System Type x64-based PC
Processor Intel® Core™2 Duo CPU T5800 @ 2.00GHz, 2000 Mhz, 2 Core(s), 2 Logical Processor(s)
BIOS Version/Date INSYDE 1.50, 8/21/2008
SMBIOS Version 2.4
Installed Physical Memory (RAM) 4.00 GB
Total Physical Memory 4.00 GB
Available Physical Memory 2.70 GB

DVD Drive;

Name ATI Mobility Radeon HD 3470
Adapter RAM 256.00 MB (268,435,456 bytes)

Aero is being used,

Problem, will only read and burn(using imgburn) the first disk, you then have to restart DVDFab in order to read the next disk. In other words if you have a series of disks to copy after each burn i have to restart Fab to read the next disk

I am currently using ImgBurn to correct a not burning issue, this is due to Vista 64(do not have any issues with Vista 32 business on desktop)

Thank you for your thoughts.
