When selectting partitioning with fdisk, an empty window appears (no initial fdisk messages) and you can only abort the installation. The configuration: 2 IDE disks hda and hdb and an ATAPI CD-ROM, hdc. I had chosen hda for partitioning.

I have seen this problem on PE1650 with Adaptec/SCSI HDD too.
it's a generic process management problem, fdisk partitioning won't work at all right now - still working on the fix.

It seems to work as expected in beta 2.
Confirmed. Tested and recieved expected results with Beta2.
