I am writing a program in Think Pascal that uses the TCL.  I have bumped 
into a few problems and solved some of them, but would like some feedback 
from others:

1) The AdustCursor method seems to get called in a loop, even though I set 
the mouseRgn correctely.  What this causes is the mouse, as well as 
another window's contents (where I write text during the method), to 
flicker and delays of update events (and others.)

2) How does one use a scroll-pane and include some extra controls in the 
scrollbar area?  My solution was to override IscrollPaneX and include the 
extra stuff there, but that doesn't seem healthy.  Do I need to do the 
whole scroll-pane bit myself (I.e. do what ScrollPane does?)

3) There seems to be too much goddam flickering during update events!  I 
can't find any way to control this.

4) Moving/Resizing an EditPane fails!  Some of the TE boxes are not 
correctly updated to reflect the new position and size of the EditPane.

Thanks in advance for any help - Yossie

P.s. is there a (semi) complete list of bugs in the TCL?  Anything would 
be useful.
