Hello,

It's me again !!
Taskcoach Portable 2.0.2.3 alpha crash when starting an effort on a new subtask.

Steps to reproduce:

1. Create a new task
2. Create a new subtask in the new task
3. Start an effort for this new subtask

Note:

• This issue came also when you want to create a new subtask using a model
• When closing the program after the creation of the subtask (with autosave settings) then opening the program again, it's possible to start an effort on the new subtask.
• This issue came also when the task view is the only one displayed (no filter view)
