Question for Prime users - GUI issues

I know prime doesn't get any love around here, but it also has many users.  Mathematically, it usually does what I want.  My top gripes are mostly about GUI issues, but I never see anyone else complaining about them -  while they make Prime almost unusable for me.  With a bit of work I've been able to get PTC to duplicate them - but they don't seem very keen on fixing them.  So, my question is - am I somehow the only one seeing this?  Other computers in our organization do the same thing so I 'm assuming it's universal.  Yet the lack of outrage is surprising.

GUI bugs:

1.)   Solve block equations - will suddenly switch to only being able to move/snap them 2 squares instead of 1 (note, I'm using the small grid pattern).  Works fine for a while and then it loses its brain and can't align with other equations.  Minor issue, but annoying.

2.) Select box does not follow the mouse when it crosses pages (when inside a collapsible area and in page view)

3.) Clicking on the screen will regularly cause the screen to jump up or down several lines or even multiple pages.  This is the big one.  How am I supposed to be able to work like this?  I do believe this is also related to working with collapsible areas.

4.) When editing long programs (>~30 lines), the typing starts to get really slow.  I can type 5 letters and have to wait 3-4 seconds for them to appear.  Same with deleting letters.  (I'll call that a GUI issue because I'm not sure what else to call it).  This really limits Prime's ability to be a serious engineering program if I can't write programs over 30 lines.

5.) In draft mode, the screen constantly shifts so that the collapse buttons become hidden behind the left hand border.

So, just trying to understand if I'm the only one.

Thanks,

(Prime 3.0 through 4.0, windows 7, multiple installs, different computers and different users)

(I should probably give up on collapsible areas, but they are too handy.)
