I have a couple of issues with JavaDoc in IntelliJ 10.5.
1) Most importantly, I don't see any documentation in the popup that should show it. If I press CTRL+Space and I narrow down the possibilities to one function (and or click CTRL+Q) I see its signiture and next to that box I see the JavaDoc popup which only says "Documentation for method()" and nothing else. If I click on the pin in top right corner, I get a big window with the actual JavaDoc.
2) If the function is my custom function inside of the same file with simple JavaDoc (just the general method description) then the big JavaDoc window is just a gray empty box (just a rectangle on top of everything) or it only shows the type and name of the method.
3) JavaDoc only shows when I trigger autocompletion by pressing CTRL+Space (I read somewhere that this the behavior and I'd strongly support such a feature request).
Additionally, the behavior of the JavaDoc window is just weird, the pinned JavaDoc window sometimes disappears, turns into the gray box or turns into the popup again.
Being able to easily see the JavaDocs is probably the number one feature of an IDE for me and I am really sad that it is so buggy in IntelliJ which I really like in other areas :(
Last but not least, I am using the Windows version on Windows 7.
Thank you for any suggestion to solving these problems.
