A 256 color bitmap. I thought colordepth 32 would be ARGB?

Sorry about this, this was at the end of my code ofcourse,
I somehow got it to moved up when i posted the message.

I thought the BITMAP class had an internal way of storing
colorvalues, so that 32bit would always be ARGB. No matter what
graphics card (mine is GBR), thats why 0x00FF5500 seemed correct
for 32bit orange. I shall have a peek in the documentation.

Thanx for showing any intrest at all!
