Hi All, When trying to launch programs written/compiled with IDL under IDL Virtual Machine, my system is completely locking up at the point at which it says %Loaded DLM: PNG.  This also occurs when trying to run the IDL Demo whenever anything is launched that uses the PNG DLM and I've noticed also the JPG DLM. This was happening with IDL VM 6.3, but continues with IDL VM 7.0 This is a linux system, running Debian Etch. Any advice, or points to the right direction would be appreciated!
