Also other tabs keep minimizing whenever I click on a tab.

In Illustrator, you can only resize palettes that are marked with ten little stogies at the bottom of the palette.

As for your second question, can you clarify? It may be solved by some preference setting.

Thanks for the help. Nvm for the second question.
