  See attached sample: it fills a C1FlexGrid in the form constructor, then switches the “Row” property to two different rows.
  
  In “OnLoad”, a theme is applied.
  
  FlexRow.zip

  This results in the vertical scrollbar being rendered wrong: the scroll thumb is rendered at the top of the scrollbar - thus it seems that the first visible row is also the first row of the grid:
  
  

  

  802×484 15.5 KB

  But after scrolling with the mouse wheel, you see that there are more rows above the selected row:
  
  

  

  802×487 15 KB

  I found two workarounds:
  
  a) after applying the theme, set “c1FlexGrid.TopRow” again
  
  b) after applying the theme, call “BeginUpdate”/“EndUpdate”.

  This happens with 4.5.2022.576 - but I think the bug was introduced some versions before, as I remember having implemented a workaround some time ago for another grid.

  Thanks!

  Something different: I don’t receive any notifications since a few months for my own posts - only for posts that I reply to. Could you take a look at this?

  Best regards

  Hi Wolfgang,

  As per the concerned team, there was some internal issue with the Email notifications, which is why the alerts were not sent for some forum posts. The Forums were under maintenance for the past few days to resolve these issues and now you should start receiving proper alerts. please let us know if the issue persists.
