Carl,I have not encountered this. This is perhaps because I have never truly put vDos+ XyWrite through the paces like you do. At the vDos forum, there is a similar use case: https://vdos.proboards.com/thread/287/clipper-maximum-windows-handles-exceeded I run some DOS Clipper programs in VirtualBox/vmWare sessions. No problems there. Normally, I use the Harbour compiler (the HMG variety) to make Windows programs.
