Hires Graphics trouble

[ludditetech@mac.com (Simon Williams)]

Still trying to get a HiRes screen to load at the start of my program.
This is what I've got:

	10 HOME
	20 PRINT CHR$ (4) "PR#3"
	30 HGR2
	40 PRINT CHR$ (4) "BLOAD MY.PICTURE, A$2000"
	50 GET GARBAGE$ 

Problem is it doesn't load very often.  Most of the time I get a
screen full of 'static'... sometimes just blank... once in a while the
picture shows up.
I noticed that sometimes a HiRes screen from a the last program pops
up... do I need to clear the memory somehow?
I've also tried BLOADing at A$4000 and even at both locations, but the
results are always the same.
Tried it on //e and //c, same results...

HELP!
All I want is a nice startup image... is that too much to ask?

PS. HiRes page was done with MOUSEPAINT, if it matters.
