Navigator pane problem

 
Ricentry I faced this problem in Navigator pane of MT 4 Built 211.

Dropping an custom indicator on the chart I've got:
Cannot open file 'E:\Programs\tools\4x\MetaTrader\experts\indicators\customIndicator.ex4' on the EURUSD,M5

And that's correct - because I deleted it.

The problem:

* File exists in Navigation pane (another existing in file system is not visible nevertheless it was created with create custom indicator menu)

Any suggestions? Thank you

Please ingnore this.

Problem was obviously in the file system lock. Restart fixed it.
