This problem is in corel photo-paint since version x3 (in v12 it was fine), and I was hoping it would be fixed in x4... but it's still there... Lets say I draw a rectangle 100x100 pixels large. I select the object and try to enter a height value manually. I enter 1 pixel for height hit enter, and the object is 2 pixels high. Why? If the object I want to scale is 2 pixels high and I enter a height-value of 50, it's scaled to 26 pixels... quite a margin of error... Scaling an object that is 1 pixels high does not work at all... Scaling to specific dimensions by pixels is something i have to do a lot, and this issue is driving me nuts! Please tell me I'm doing something wrong here, and that there is an easy solution to this! A different issue that also appeared in x3 (that seems to be fixed in x4) is, when I scale an object (usually when i stretch it), even if the original object had just one color (say I had a gray rectangle), there would suddenly be collor-variations in the streched object, which in rare cases would be visible to the eye, but in most cases could be picked up with the color-picker if you picked the color from a few positions...

Do you have your outline set to none?

When I do your test, I do get a two pixel rectangle. When I turn the outline off, it is one pixel again.

I was talking about corel photo-paint and not corel draw. (to my knowledge) objects in photo-paint don't have outlines (or am I missing a toolbar or docker?). You can have borders when drawing rectangles, but those borders are rendered as part of the object, and they can't be changed afterwards. Using borders does not influence the behaviour. If there is such an outline setting in photo-paint, could you please tell me where it is?

I was speaking of Draw and wasn't aware that Borders on Rectangles in PP behave differently. 

If I change the size of a rectangle to one pixel high I get two pixels. If I reenter the 1 pixel for the height it sticks.

You can also drag to one pixel in height. As nearly as I can tell there are no scaling issues once it sticks.

I noticed in PP I can only stretch an object vertically with the top handle. The bottom handle scales the entire object. Huge BUG!

Works perfectly fine here, try again! There is no BUG!

Hmmm... I am having problems recreating it today. However now I can't strech anything 1 pixel in height.
