There is a big delay(about 25 seconds) in windows Explorer to show big red Delete X button and History button in toolbar when selecting files. The big RED delete X(not the close x) button is dim and becomes red after almost 25 sec's and same thing happens to history button. By that time Right click select Delete for this file works ok. This happens only first time opening a folder and even if operating system is on for a long time.
