From the nature of your thread question is sounds like your program is some version of Photoshop Elements. If that is the case, you have posted in the wrong forum. Some how your post got posted in the Adobe Premiere Elements Forum (video editing). Please re-post your thread in the Adobe Photoshop Elements Forum to take advantage of the specialized expertise there.
As a side note, I have used the Crop Tool in Photoshop Elements 14/14.1 Editor Expert workspace and, if I set for Crop Tool's Custom with custom width/height setting, it stays that way, until I hit Reset Tool or Reset All Tools. Please give more details, including computer operating system in your thread re-post in the Adobe Photoshop Elements Forum.
We will be watching for your progress.
