| Summary | 0016246: Edit Color property in Lazarus causes Div by zero | ||||
| Description | Clicking Color property of objects cause div by zero crash error. If i click to ignore the error and continue in IDE the problem doesn't appear anymore and color list and dialog comes up nicely. | ||||
| Steps To Reproduce | Start Lazarus and make a new empty application, click form's Color property. This causes division by zero which wants to crash the IDE. I tried to find the limits to this error so i tried font.color etc. "Some" don't seem to give the error but form always does, that 1 time. If i happen to get color property clicked properly once from other object then even form doesn't give error. | ||||
| Additional Information | This only appeared after installing latest Lazarus daily snapshot. | ||||

This seems to be yet another NewAutoSize 'regression'. |
