Do I need a pause?

[tazntex]

I've added a 250ms pause after high one and it seemed to be a little better, then I add a 500ms pause and it does not stick so much although this is not a cure.
oop3:
if mydata1=%01011001 then
high 1 'portb.1 is on
pause 500
else
low 1 'portb.1 is off
endif
GOTO loop

Loop2 does fine its just noticable in loop3. I thought there might me something with PICBASIC PRO 2.50, i've already installed the A patch and went there today and they have a 2.50b patch. I didn't see anything that might affect what I am trying to accomplish here. I know there are a lot of people here on this forum with much, much more experience with microcontrollers than I'll ever have. I have search time and again to see if anyone has had similar problems but have not not found anything revelant to this type. Certainly someone sees what I have missed. Thank you
