I tried on several computers with windows 98 windows nt4 windows 2000 to run gem. In vain. I must say that I get pd running on all of them. while typing f:pd\bin\pd -lib f:/pd/gem/Gem I just go back to the cursor. Some people are talking about "puting pd or gem/Gem 'to the path'". I do not know how to do that and where to do it. I put in win98 something like path=f:\pd but it didn't help me a bit... could you please help me? eric Feremans
