LFS Configuration - Invalid Cache Size

Hi, I appreciate the writeup on mounting a binary file. The OFSMount utillity works great.

I however am running into an issue with setting up the Explorer.

Here is the configuration of my LFS onto an 8MB flash chip.
.read_size = 256, .prog_size = 256, .block_size = 1024 * 4, .block_count = 2048, .cache_size = 256, .lookahead_size = 512, // must be multiple of 32 .block_cycles = 1000, //Highly suggested to set block_cycles in the range of 100-1000.

I think my configuration is valid, but please let me know if I am missing something.
Thanks,
Jeff

Issue with opening files

I use SD card with block and read and write size with 512 bytes. When I open the explorer and select the littlefs formatted sdcard on the left pane, opening the first file (that is a .txt) is ok, but after closing and reopening it or opening another file, I encounter with lots of warning popups with message: "could not update the opened file 'blah blah' removing the file from the update list. your changes will not be updated.".
If I refresh the explorer everytime I close a file, this popup won't appear. It seems there is a bug in this situation.
