That depends on the program involved, and any other device drivers and TSRs you load. Some programs require that they are the first to catch an interrupt line, and some require to be the last. If that matters with your particular program, that will help decide the issue. Also, you may have other device drivers which must run before or after your program, and the same could hold true for TSRs of yours. In general, though, for a mouse driver it's probably best to load it in as early as possible, so use the device driver. Mickey Ferguson -- Rolm Systems -- FergusoM at scrvm2 -- mickeyf@vnet.ibm.com
