Hi, The bug applies to 1.3.0pre3, whith any frontend.
The attached file contains some gather math environments. It could be any math environment with multiple rows, eg. eqnarray. In any of them, try to select with the mouse the whole middle row. As you move the mouse (with the first button pressed), the first or the third row also get selected, ie. there is no "central range" to place the pointer such that the selection takes place only in the middle row. Note that there is a "central line" in the middle row. If the cursor is above it, then the first row gets selected; if the cursor is below it, then the third row gets selected. _But_, the line is not centered in the middle row, it is half cursor below its center, which constitutes another "feature" of the bug. The problem is not serious because if you continue to move the mouse to the end of the middle row, then the selection becomes only on it, but it is annoying and can confuse beginners. André, if you want me to file a bug in bugzilla, please suggest a Summary that can identify it. I can't even describe it well! Regards, João.
