Hi Team,
We are using PQ Grid and got an upgrade from version 6.x to 8.x recently.
In the version 8.x, the "frozen columns" does not work properly with the vertical scrollbar.
After columns are frozen, then scrolling the vertical scrollbar, cells in the frozen area or the whole rows can not be selected anymore.
If we unfrozen the columns, cells can be selected again, but the whole rows are still not be selected.
This issue just happened in version 8.x.
You can confirm by the demo as steps below.
<https://paramquery.com/pro/demos>
1. At "Demos" menu -> select "Demos 8.x" -> At the left Menu, select "Frozen columns".
2. At "Total frozen columns" dropdown, select a number which is not "0". For exam, select "3".
3. Mouse click some frozen cells in the left frozen panel or select a whole row, the cell or row is selected as normal.
Then scroll the vertical scrollbar up and down repeatedly.
4. Mouse click some frozen cells in the left frozen panel or select a whole row again, the cell or row is NOT selected any more.
5. At "Total frozen columns" dropdown, select "0" to unfreeze the columns. Cells can be selected again, but the whole rows are still not be selected.
Please confirm and give us some advice or solutions! Thank you very much!
