Windows form problem in Win 98

I have a c# Windows Forms application that seems to work
fine in Windows 2000 and Windows XP. However I have three
problems in Windows 98.

1) On a form with about 200 data bound controls when I try
to open a dialog form I get an error. Message = Invalid
Parameter Used. Source = System.Drawing

2) On Some forms the drop down box does not show an arrow
but shows a number 6.

3) In large forms the font I use for runtime created
controls changes to a bold font after a variable quantity
of controls

4) Even though there is 512Mb memory in the machine it
will not run other software at the same time or runs it so
slow it is useless.

These problems only occur on Win 98 machines. This is
causing major problems as some legacy software requires
Win 9x to run. I have tried playing wth virtual memory but
this seems to make no difference.

Any ideas as Microsoft now refuse to support Win 98 even
if I am paying for a support call.
