The problem:-For some inexplicable reason drag and drop has stopped working.
The Resolution:-If some one faces the above problem in Windows XP then I shall suggest him to do the followings:-
1]Sometimes just a system reboot solves the issue.So try that first.
2]Check whether Drag and Drop is enabled or not.Right click on Start button>Properties>Start Menu>Customize>Advanced>Under the start menu items make sure the box against Enable dragging and dropping is checked.
3]If the above fails then try a System Restore.
4]If nothing helps,then type the following commands from the Run menu.:-
i>Start>Run>type in-"regsvr32 ole32.dll "(without the quotes)>press the Enter Key or OK.
ii>Start>Run>type in-"regsvr32 /i shell32.dll "(without quotes)>press the Enter
5]Restart the computer.
