IDV and McIDAS-V cannot create graphic interface under 11.2

Upgrading from 11.1 to 11.2 I realise that neither IDV (from Unidata) nor McIDAS-V (from SSEC) fail to create their graphic interface and crash without further notice. Both are Java-based applications. I am running 64-bit 11.2 on a Compaq 8510p with ATI Mobility Radeon HD2600 graphic card
