... the rest deleted.

Looking at things a bit more, I notice that one of my widgets is running
much slower (a factor of 2 or more) and is now flickering. I traced this
"problem" to a point in the program where I am plotting calculations on the
fly and displaying some updated information in a WIDGET_TEXT field. It
appears that the formerly smooth operation of the following line under IDL
V3.6.1 has been changed in some way under V4.0.

widget_control,wids(2),set_value=curtim

For some reason, updating the value of a WIDGET_TEXT of a realized widget
now consumes enormous resources (It takes as much time to update the field
as it does to perform the complex orbital caclulations I am doing) and in
the process also causes my widget to flicker now. This is most annoying
and unacceptable.

Based on this and what I have read in this group, I reccommend that current
users do not upgrade to V4.0

OH BTW, I have gotten wind of a new maintanence policy from the folks at
RSI. In addition to a price hike, they are now charging floating network
sites for each and every license in the site (they used to charge by the
site). So, for a 6 license site running under OSF the annual maintanence
has gone from $250 to $2250 ($375 * 6) per year. So plan your budgets
accordingly.

Time to look again at that site license from PV WAVE. Since I have
to rewrite that code anyway to work under IDL V4.0, I might as well
consider my alternatives.
