I work with R+RStudio some years ago perfectly. Since Posit has introduced some changes in RStudio I have some problems. Firstly the screen of RStudio didn't fit with the screen of my PC. On the top and on the sides there were spaces out of my screen. I have deinstalled and reinstalled several times so R as RStudio and finally what I got, and it is not enugh, is: on entering RStudio I get the two right pades (Environment and "Miscellaneous", upper and lower pades) appear, but the rest of the half screen is in blanc, just on the top left appear two lines: New File- Delete- Rename- More (Copy, Copy to Move...).The screen of RStudio now fits OK with the screen of my PC. I have moved the files from documents, looking the case of some of these files could cause this issue. Everything keeps being the same. I have for R R.453 and for RStudio RS 2026.01.1. What could I do for getting again the four pades? Thank you very much.
