CorelDRAW Graphics Suite X5 :: Marquee Select / Weld Text To Line

When i use margue select i get the blue dotted line but it disapears when i let go of the mouse and nothing is selected,  this happens no mater what i'm trying to select.  Do i not understanding how it works? 

Second dumb question.

I have hit or miss luck with the weld feature some times it works and other times it simply will not work.  I'm trying to make a small metal sign and need solid numbers (not Stencil) I draw a rectangle and add text above it and move it down to the top of the rectangle and select both and hit weld, some times it works and some times it doesn't.  I have also tried to weld text to a 2 point line and cant do that at all, I suspect the 2 poing line is considered a demensional line so that may be my problem there.  I have spent the greater part of a day trying to figue out thes two problems I have watched Graphics unleshed and read all i can find and still haven't figured out if it is me or the program. I have the problem with any of the fonts that come with X5.
