Disappearing Controls on tAdvToolPanel

When a control on a tAdvToolPanel has the Anchor set to Bottom it disappears when the panel is rolled out from a tAdvToolPanelTab. At some point on the RollOut, the tool panel height is set large and the control follows it "down" then the panel is sized back to the "Height" property value, but the bottom anchored component stays below the bottom of the panel. This can be replicated on a very simple form. Tool Panel version 1.8.3.0

Technically, when the panel rolls out, the panel height is animated from zero to the final height and apparently this disturbs anchoring. Not sure how we will be able to address this, we need to investigate deeper.

Thanks for the reply, Bruno. There is a simple work around by saving a tRect for each control before RollOut and resetting the control position afterwards, so no real urgency for a fix. BTW there is also a similar issue with controls that are Top aligned in the panel. I have a top aligned chart that ends up taller than the panel after rollout.

Bruno - this still seems to be happening. Did you manage to identify a fix?

Sorry, we haven't been able to find a workaround for this strange/unexpected behavior in the VCL anchoring code.
