Symptoms

Adding Sub-Control Plan Nodes (SCPN) to the Contol Plan Editor (CPE) canvas causes the CPE to become slow and unresponsive, with delays increasing significantly as more and more SCPNs are added to a control plan.

The issue can be reproduced at will with the following steps:

1. Add SPCN to a control plan and configure it.
2. CPE slowness becomes noticable as soon as:
   - a node or note is re-sized
   - a node is saved
   - an exit is modified
3. Adding more SCPNs greatly increases the CPE's unresponsiveness.
4. The only way to know that the CPE is usable again is when its Inspector panel starts changing as you move the cursor over node exits, etc.

The impact of this is that once one or more SCPN nodes are added to a control plan, it rapidly becomes impossible to efficiently use the CPE to modify the control plan, with delays rapidly spiralling up to massive lengths.

Changes

Installing or upgrading to NCC versions 5.0.0.1 or 5.0.0.2 (Intrepid Patch set 1 or 2).
