Description:
Opening blob field data (containing 65k jpg image) in Value Editor takes 10-40 sec (depends of previous selected tab in window "Edit Data for") to complete while GUI completely hanging.
There was no such issue in previous version.

How to repeat:
Create table with blob column, add some jpeg picture to it and try to observe it using Value Editor.
