I haven't used sliders much (ok- I've only ever used them in the last 5 
minutes ...), so need to ask for a bit more info.

I don't see any problem with the numbers lining up - the min and max 
values look to be fully aligned, and the "current value" box is aligned 
with the top of the min text (which means the actual characters are down 
a few pixels). Is that the problem - or is there something I haven't 
seen yet ?   If it the alignment of current with min/max, it's almost 
certainly a wxWidgets issue.

I'm pretty sure that'll be part of the general resizing problem - fixed 
in the experimental resource editor. I'm hoping it proves to be both 
stable and popular enough to replace the current resource Editor - but 
even if it isn't, the 2 or 3 actual bug fixes found so far will be 
backported to the current one.

I've never got completely stuck in the dialog - I can always get out 
after 2 or three tries, and changing the name back to a valid one let's 
me carry on.

Currently, "_" is disallowed in component names - but the checks are 
incomplete, so they can slip through in some places. (As a workaround, 
you can use Copy/Paste to create a new component with the name you want, 
rather than renaming the  existing component).

The reason for this restriction is because the "_"s are used to pick 
apart names for the automatic event binding. I suspect that it would be 
possible to (partially) relax this restriction.

However, I believe that we should keep the restriction that component 
names must not start with an underscore (and perhaps also that they must 
not finish with one).  Would your names be OK with that restriction ?

Doesn't seem like it - it was there at least as early as 0.7.3 
(according to the docs - I didn't really use anything earlier than 0.8, 
so can't confirm it).

No (except for the resizing issue).  And the naming restriction seems 
like it should be easily fixable.

The alignment might be.
The problem of needing to click in the main (slider) part to select the 
component to move it is (indirectly) a wxWidget problem.
The name restriction certainly isn't.
