The filter in the data tab of the object explorer can only be used once. (4239448)

There seems to be a defect with the filter in the Data tab of the Object Explorer. It can be used once, but any time a filter is set after that, it does not apply.

WORKAROUND

Close the right side of the Object Explorer and re-open it. This will allow you to set a new filter

STATUS

Waiting for release of fix in a future version of Toad Data Point.

Here are steps to replicate:
1) Open Object Explorerer and highlight a table.
2) On the right hand side, select the Data tab.
3) Click the filter button in the toolbar of the Data tab and set a filter. You will see this filter applies with no problem.
4) Click the filter button again and set another filter. You will see that this one does not apply.
