Hi David,
Think I can answer these two questions for you.

Vince is correct. The IDL Workbench is parsing all the PRO code on your
path, in the current directory, in your open projects, and editors. If
you're similar to our ENVI developers, it can take a while to do all
that! I've already taken quite a bit of ribbing on this, so the plan is
to speed it up. Still, it shouldn't adversely affect the user's ability
to use the IDE. All the processing is done in background threads.
Depending on how much PRO code you have, whether it's over the network,
etc., I think a typical amount of time is a minute or so.
One thing to note is that before it finishes, you might not get every
routine chromacoded, be able to do "open declaration", get content
assist, etc. Once a routine is discovered, that type of functionality
is available for that routine, editors will redraw, etc.
Closed projects are not parsed, so there is an incentive to organize
code into projects. ;-) As Chris mentioned in another thread, projects
can be simple links to existing directories, so one doesn't actually
need to reorganize their files out on disk. (See the "Create the new
project from an existing directory" option in the "New Project" dialog.
If you don't want the IDL Workbench to automatically add that project
to your path, just uncheck that option.)

This is a known issue and is being tracked in our bug database.

Sure thing. Keep the questions coming - we like good feedback.
Cheers,
Doug
