Series marks OnTop causes TList error

[Toreba]

Using TeeChart Pro v2011.03.30407 W32 with Delphi 2007, if I set Marks Visible and OnTop, then all works fine until I zoom beyond the extents of the data (at least beyond the maximum x value). Then I generally get the error 'List Index out of bounds (-1)' from somewhere within the TChart code. If I switch off 'OnTop' then the error disappears. Is this a known bug? It's easy to reproduce in a small demo I have if you need to see it.

Hello Trobea,

There are a newest maintenance release of TeechartVCL, as explain here. I suggest you update your version and try again if your problem appears. On the other hand, if you problem still appears If you can send us your project, we would be very helpful for us to check where the problem occurs.
