The original problem is still present: for some documents, when I click on the text, some text is selected for no apparent reason when I use TSRichView (but not when I use TRichView). I have e-mailed a sample project, document and source code.
Problems with this document are caused by incorrect (negative) value of the bottom margin (it equals to approx -42 mm).
Please correct it and do not allow incorrect values in future.
On our side, we will add changes allowing to process invalid margins without glitches.
