I'm using ideStatik 6.54, I recently upgraded my operating system from 32bit Vista to 64bit 7, the hardware I use hasn't changed. In drawing mode, the program gets very tight, especially when moving large objects, for example, when moving a mold plan or curtain opening, I didn't have such a problem in the old operating system, which is more evident in drawings such as the reinforcement table. I wonder why when moving an object in drawing mode in ideStatik program, can the shadow (ghost, projection, preview) of the moved drawing be prevented?
