During a multi exploration I began to check the results of completed explorations - after a few clicks on the new exploration window, MetaStock crashed no on-screen error message.  Checking Windows event viewer, I found three event errors attributed to MetaStock - listed below.

Please let me know if you need more info for debugging.

Thanks

No problem, guess I'll have to sit on my hands whilst the exploration is running :-)
