Please note that there is a bug in this release: The problem is that certain file names are being misinterpreted as if they are command arguments. Examples of file names where this happens are ones containing a space followed by a number, a "C", "G", "B" or "K". When this happens MLwiN is unable to open or save the file, giving a "Wrong Params" error. The complete file name including the path could be misinterpreted.
The workaround is to either rename and/or move the file so that it does not match the above criteria, or to open the command interface and click the most recent line starting with "LOAD" or "STOR". The user must then replace the "LOAD" or "STOR" command with one appropriate for the type of worksheet and press enter to run them command. The appropriate replacements are as follows:
| LOAD | STOR | |
| MLwiN | RETR | SAVE |
| MLwiN (compressed) | ZRET | ZSAV |
| Stata | RSTA | SSTA |
| Minitab | RMTW | SMTW |
| SPSS | RSPS | SSPS |
We apologise for any inconvenience this may cause. This bug will be fixed in the next release.

Running multivariate discrete response models from a macro gave different results to running from the GUI when binomial (as opposed to extra-binomial) variation was specified for any response(s) other than the last response. This was because when these models were run from a macro, only the last random parameter was constrained, and so extra-binomial variation would be used for all but the last response regardless of the user's specification. Thus if the user wanted to fit, say, a trivariate binomial response model with all responses having binomial variation, then if the user ran the model from a macro the first two responses would fit extra binomial variation and the third response would estimate binomial variation. If the user instead used the user interface all three responses would be fit with binomial variation as required.

MLwiN crashes when editing data. This is caused by the cursor moving to the next line after you finishing editing the data. If there isn't a visible cell to move to the application will crash. Workaround: A temporary solution is to resize/scroll the data window so that there is always a visible cell below that which you are editing.
Attempting to save to a read-only device causes MLwiN to crash
MLwiN crashes when Paste window minimised.
If the user selects Edit > paste and then attempts to minimise the resulting window MLwiN will crash with a runtime error.This is caused by window resizing code being able to be run while there is no window visible to resize.
Incomplete line in input file causes problems.
If the user attempts to import delimited data where some of the rows do not have data or delimiters for every column MLwiN will import fewer than expected rows and place data in the wrong column.
While it can be argued that such input files are invalid, unfortunately Microsoft Excel produces such data when the user attempt to paste data containing blanks at the end of the last column.
