************************************
* Known bugs in LEMWIN and LEM 1.0 *
************************************

1. Folder names:
- LEMWIN cannot deal with directory/folder names containing a space like 
  "c:\program files\lemwin". It will not be able to find relevant files. 
- Solution: install the program in, for example, "c:\lemwin". 

2. Working directory/folder:
- There are sometimes problems in finding directory/folder with the data 
  files. You get a strange error message. 
- Solution: save the input file in the directory/folder with the data file.

3. After 9999 iteration:
- Output to screen is not correct after 9999 iteration. Also the 
  ProgressBar disappears.
- Solution: set log off.

4. File names:
- An error message is given if you use a command as file name: for example, 
  "wla latprob.txt". Note that "lat" is a command.
- Solution: don't use such names.

5. Computation of standard errors:
- A runtime error occurs in models with in between 150 and 180 parameters. 
  The program should not give standard errors with more than 150 parameters.
- Solution: suppress standard errors with command "nse". 

6. Statistics:
- Dissimilarity index may be incorrect in large tables.
- Degrees of freedom and p value may be incorrect in extremely large tables.
- Solution: no.

7. Command lin():
- A runtime error occurs when lin() is used in all {}. 
- Solution: no.

8. RC(M) models:
- Singular value is not performed in RC(M) models. 
- Solution: write fitted table to a file and estimate an association model 
  with the cor() option using the fitted table as data.

9. RC models:
- There may be problems with equality constraints across groups in model 
  types c, d, en e.
- Solution: no.

10. Event history analysis with a discrete-time logit model (command "dis"):
- Problems occur when observation have t0 = t1. 
- Problems occur when observed survival times are larger than upper limit 
  of the last time category.
- Degrees of freedom are not correct.
- Does not work correctly with multivariate hazards (command "mult").
- Solution: no.

11. Command eq1:
- Does not work with cumulative link functions; that is, command "cum()".
- Solution: specify constraints across submodels via all {}.

12. Command wma: 
- Runtime error 217 is reported with very large tables.
- Solution: no.

13. Continuous covariates: 
- Problems occur when continuous covariates are used in all {}.
- Solution: no.

14. DOS version LEM.EXE:
- Because of an error in the Borland Pascal compiler, the DOS version doesn't
  run on newer computers (runtime error 200).
- Solution: search on the internet for tppatch.zip, a program that fixes the 
  problem with LEM.EXE.
