Hi Sarah,

I haven't had this experience and I've been coding in vb .net for almost 2
years now. I do have a stronger system than you do (gig ram), and you
didnlt mention your op sys (I'm using xp pro), but that really shouldn't be
that significant.

I'd recommend you stop using other color schemes and use only xp visual
styles (if you have xp) to see if this doesn't change matters. Also, are
your forms loading lots of data on start up of a form? (eg, comboboxes
loading thousands of rows, etc), although this ordinarily also should not be
a big deal.

HTH,

Bernie Yaeger
