I was having problems with my PC earlier — couldn’t drag and drop files and couldn’t move icon on desktop. I thought it was caused by Adobe PS which I used early yesterday morning. An error occurred, forcing me to restart the program. Then whenever I moved a text layer on an image, it keeps going back to its original position. I didn’t restart my computer until I got home to test my newly bought DSTT (YAY!). That’s when I realized I couldn’t drag and drop files to the micro SD. I tweaked the registry a bit, restarted the computer a number of times, and did a cold boot. Nothing worked! >_< I was getting pissed off and worried because I didn’t want to reformat my computer yet. Then I came across this blog. He had a similar problem. Read here what caused it and the solution. Goodness! I can’t believe it’s just THAT.
