[Bluej-discuss] Do people use BlueJ under Win98?

[Davin McCall]

Hi Daniel,

I don't think very many people use BlueJ under Windows 98, though 
occasionally we get some support requests from people doing so. I don't 
think I've heard of this particular problem before (does it happen on 
all the 98 machines you installed it on?).

It sounds more like a problem with Windows 98 than a problem with BlueJ, 
because as you say it works under Windows XP and it also works well 
under Linux and MacOS. The "toggleBreakpoint" code is not operating 
system specific i.e. if it works under one operating system it should 
really work under them all.

I know that Win98 is somewhat more usable on old machines with limited 
memory than is WinXP for instance, but I'd personally recommend keeping 
clear of 98 unless absolutely necessary. Microsoft have already extended 
the "end-of-life" for 98 once but I suspect that its days are numbered.
