Build: NetBeans IDE 8.1 (Build 201510222201)

OS: Windows 7

User Comments:
GUEST: U/K

GUEST: Just scrolling through the code.

GUEST: I have no what caused it. And second thing, it is possible to run multiple instances of program, but it does not take into account changes in the program, so all instances are the same.

GUEST: Netbeans in Windows Remote Desktop: After close and reopen of Windows Remote Desktop, in the Netbeans, right header of code panel is white (no line numbers, debug breakpoints...), mouse wheel does not work in the code panel (but it work in the output panel).

GUEST: unknow

ferrybig: Unlocked computer from windows lock screen

GUEST: browsing code

GUEST: Wasn't really doing anything. Just had different java projects/programs open.

GUEST: Went to scroll down code using mouse wheel

GUEST: Made code changes and compiled.

GUEST: I have not idea... maybe could be important that it is via Remote Desktop Connection.

GUEST: <Please provide a description of the problem or the steps to reproduce>l

GUEST: Looking through source code.
