Hi Henry,
Good that you supplied a test program. You do not give any intitial
VALUE in the CW_SLIDER() function (The default, I guess, was 0 and this
did not lie between your min and max, I don't know why it worked with
the FLOAT) . I added it like:

mid= min+(max-min)/2.0d
slider = cw_fslider(base,min=min,max=max,VALUE=mid)

And it worked. I also recall reading somewhere that the event handler
function should be above the main code. This doesn't affect your error,
I think, but may appear when you least expect it (like exiting IDL and
re-entering it)
